Born into the wealthy family of Chief C.Y and Dr Mrs. P. AN Onwubuariri on the 7th day of July in 1981, a third child in a family of nine children among which 5 are boys.
His father being a retired Principal and currently the traditional Prime Minister of Amato-Amaraku Autonomous Community, and the mother also a retired Principal but very much devout and committed with the things of God. These two backgrounds shaped and molded young Barr. Chijioke into what and who he is today.
Armed with these, he started his educational pursuit very early in life, thus he attended Umunkwo Primary School between 1987-1993 where he got his First School Leaving Certificate. In 1994, he proceeded to the Innocent Comprehensive Secondary School Ijeshatedo Lagos and got his SSCE in the year 2000, with four distinctions and five credits. Barr Chijioke Onwubuariri did not stop there as he passed his jamb and immediately secured admission to study Law at one of the most popular higher education institution in Nigeria - Abia State University, Uturu.
He graduated in the year 2008 with Second Class Honours, Upper Division and same feat was achieved at the Nigerian law school, Kano State province and was immediately called to bar on 4th September, 2009. Soon after, he went ahead to serve the fatherland in Osun State, Nigeria under the NYSC Scheme. He secured his Discharge Certificate and without wasting time went into legal practice. To add practical experience to his knowledge from classroom and textbooks models, he got attached to IBB Madubuko & Co Chambers at its then Okigwe road office in Owerri. Being a very brilliant and smart young man, Barr CJ as he is fondly called learnt under little or no supervision. And while on tutelage, he served reasonable under his erstwhile principal, I. B. B Madubuko (Esq.) and left a mark in that chamber.
However, with the weight is experience he acquired at school and while on tutelage coupled with his love for human right and social social justice, he did not waste time in opening his own firm, Onwubuariri and Onwubuariri Law Consult (Opinion Chambers) here in Owerri at 43 Okigwe Road, and as at today, Onwubuariri and Onwubuariri Consult is a household name within Imo State and it's environs.

Back home, he is the unsung hero of the Onwubuariri Dynasty. His love for the youth and zeal for poverty eradication, youth and women emancipation and good governance led him into founding a notable association called Yagazie Obodo Dinma Association of Nigeria.
